3. Methyl ethyl ketone peroxide - Wikipedia

   en.wikipedia.org/wiki/Methyl_ethyl_ketone_peroxide

   Solutions of 30 to 40% MEKP are used in industry and by hobbyists as catalyst to initiate the crosslinking of unsaturated polyester resins used in fiberglass, and casting. For this application, MEKP often is dissolved in a phlegmatizer such as dimethyl phthalate , cyclohexane peroxide , [ clarification needed ] or diallyl phthalate [ de ] to ...

4. Polyester resin - Wikipedia

   en.wikipedia.org/wiki/Polyester_resin

   Polyester resins are synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Maleic anhydride is a commonly used raw material with diacid functionality in unsaturated polyester resins. [1] Unsaturated polyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers.

   Many resin types may be used in pultrusion including polyester, polyurethane, vinylester and epoxy. Resin provides the resistance to the environment, (i.e., the corrosion resistance, the UV resistance, the impact resistance, etc.) and the glass provides strength, in addition to safety from fire.

   In the natural stone sector the most frequently implemented adhesive systems are based on epoxy resins (EP resins) and unsaturated polyester resins (UP resins) as well as acrylic resins, methacrylate resins and polyurethane systems (PUR resins). However, there are also products which are a combination of two types of resin, e.g. epoxy acrylate.

   The quantity used for the curing of UP resins is about 1-2%. [ 2 ] A disadvantage, particularly in the production of polymers for applications in the food or cosmetics sector, is the possible formation of benzene as a decomposition product which can diffuse out of the polymer (for example, an LDPE packaging film).
